All right, I know that you aren't really supposed to play with your cats with your hands and feet. But...I've always played with my cat this way. And other ways which probably encourage aggressive behavior, like sticking my hand in a plastic bag and swishing it around until he attacks it...he just doesn't like "normal" toys like bouncing mice, catnip, string, etc. That's all find, but my cat has gotten more aggressive by leaps and bounds. He sometimes sleeps at the foot of the bed and wakes me up from time to time by biting my feet - hard - ears back, the whole works. Sometimes when I'm petting him, he'll be purring and everything is fine, and suddenly the ears go back and he bites - hard. This is not overstimulation by petting or "love bites." Then he jumps back, slinks down to the ground, pupils huge, ears down, like he's going to attack me. I *KNOW* that the way I've played with him is probably not the best and that I've encouraged this behavior. My question is this...will he be aggressive like this for life??? He's just 2 years old. Thank you for any advice that you have!!!!!!!!!!!!1
